Review and consider all of the follow-
ing conditions before installation:
• Dimensions of the unit: 34.1 in.
(867 mm) x 19.4 in. (494 mm)
• For surface installation, the unit re-
quires a minimum of 2 wall studs in
order to ensure secure installation.
For other installation methods,
suitable framing is required.
There are three possible mounting
methods:
• Surface mount (pg. 10);
• Partial Recessed (pg. 11);
• Flush mount (pg. 12),
and any of these have the option of
being hard-wired or plugged directly
into the wall outlet.
!NOTE: If the desired replace
location is on an exterior wall the unit
should only be surface mounted. If an
in-wall or ush mount look is desired
build the interior wall out into the
room.
!NOTE 1: A 15 Amp, 120 Volt
circuit is required. A dedicated circuit
is preferred but not essential in all
cases. A dedicated circuit will be
required if, after installation, the
circuit breaker trips or fuse blows on
a regular basis when the heater is op-
erating. Additional appliances on the
same circuit may exceed the current
rating of the circuit breaker.
